John Blanchard stood up from the bench, straightened his Army uniform, and studied the crowd of people making their way through Grand Central Station. He looked for the girl whose heart he knew, but whose face he didn't, the girl with the rose.

    His interest in her had begun thirteen months before in a Florida library. Taking a book off the shelf he found himself intrigued, not with the words of the book, but with the notes penciled in the margin. The soft handwriting reflected a thoughtful soul and insightful mind. In the front of the book, he discovered the previous owner's name, Miss Hollis Maynell. With time and effort he located her address. She lived in New York City. He wrote her a letter introducing himself and inviting her to correspond. The next day he was shipped overseas for service in World War II.

    During the next year and one month the two grew to know each other through the mail. Each letter was a seed falling on a fertile heart. A romance was budding. Blanchard requested a photograph, but she refused. She felt that if he really cared, it wouldn't matter what she looked like.

    When the day finally came for him to return from Europe, they scheduled their first meeting -- 7:00 PM at the Grand Central Station in New York. “You'll recognize me,” she wrote, “by the red rose I'll be wearing on my lapel.” So at 7:00 he was in the station looking for a girl whose heart he loved, but whose face he'd never seen.

    I'll let Mr. Blanchard tell you what happened: A young woman was coming toward me, her figure long and slim. Her blonde hair lay back in curls from her delicate ears; her eyes were blue as flowers. Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive. I started toward her, entirely forgetting to notice that she was not wearing a rose. As I moved, a small, attractive smile curved her lips. “Going my way, sailor?” she murmured.

    Almost uncontrollably I made one step closer to her, and then I saw Hollis Maynell. She was standing almost directly behind the girl. A woman well past 40, she had graying hair tucked under a worn hat. She was more than plump, her thick-ankled feet thrust into low-heeled shoes. The girl in the green suit was walking quickly away. I felt as though I was split in two, so keen was my desire to follow her, and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own.

    And there she stood. Her pale, plump face was gentle and sensible, her gray eyes had a warm and kindly twinkle. I did not hesitate. My fingers gripped the small worn blue leather copy of the book that was to identify me to her.

    This would not be love, but it would be something precious, something perhaps even better than love, a friendship for which I had been and must ever be grateful. I squared my shoulders and saluted and held out the book to the woman, even though while I spoke I felt choked by the bitterness of my disappointment. “I'm Lieutenant（中尉）John Blanchard, and you must be Miss Maynell. I am so glad you could meet me; may I take you to dinner?”

    The woman's face broadened into a tolerant smile. “I don't know what this is about, son,” she answered, “but the young lady in the green suit who just went by, she begged me to wear this rose on my coat. And she said if you were to ask me out to dinner, I should go and tell you that she is waiting for you in the big restaurant across the street. She said it was some kind of test!”

    It's not difficult to understand and admire Miss Maynell's wisdom. The true nature of a heart is seen in its response to the unattractive. “Tell me whom you love,” Houssaye wrote, “And I will tell you who you are.”

    Proper diet and regular exercise seem to be the only methods for losing weight.However,the importance of water should be added in the process.While medical science has proven the positive effects of water,most people still do not drink enough each day.

    The reason why water is so important for weight loss has something to do with metabolism（新陈代谢）of fat. The liver（肝脏）is in charge of this process when it comes to turning stored fat in-to energy.However,the liver is also responsible for helping the kidneys（肾脏）that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So,drinking water allows the kidneys to focus on their job and the liver to focus on its job.

    Also,studies have shown that water can make us feel full when drunk before meals.Without even making an effort,most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach.

    Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body,weight loss goals can be achieved with greater ease.

    A latest research led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Hou. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analyzed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we're also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors, "explained Prof Hou.

    In 2010 I left the United States for the first time to fly over 9,000 miles to Uganda, a country in recovery from civil war. I was going there to help the local kids learn soccer.

    As I played soccer with some kids, the sun burned my skin. I took many breaks to drink from my water bottle before realizing I was the only one who did that. All the energetic children running around never stopped to get water. After looking around, I realized there was NOWHERE for them to get water, and there was no well or water pump in sight.

    I asked a man who was traveling with us why the kids didn't ever stop to drink water. He told me that they would have to walk all the way to the pump in the next village and they didn't want to miss out on playing soccer with a real ball. The kids seemed happy but it was not fair that to get a drink of water meant they would miss out on such a rare occurrence of playing with an actual soccer ball.

    When I got home, I spoke with other people about kids in Uganda. They told me to do something to help them. That sounded like a great idea, but how? I spoke with my friends about helping kids in Uganda. We decided that we could try to solve their most urgent problem—water. And we decided to organize soccer camps to collect money.

    It has been three years since our first camp and we have successfully run two more and funded two water filtration (净化) systems as well as 60 water pumps for farmers. We have been able to improve the health of thousands of Ugandans.

    We often ask these questions: Are African wild dogs really dogs? What's the difference between African wild dogs and the dogs we know as pets? For one thing, African wild dogs, which live in Africa, only have four toes, while domestic(驯养的）dogs and wolves have five. But you won't want to count for yourself, because they are truly wild animals.

    “Wild dogs are not somebody's domestic dogs that ran away and didn't come back, although some people used to think that,” explains Dr. MeNutt, who studies these animals at Wild Dog Research Camp in the African country of Botswana. “They are actually Africa's wolves, and just like wolves, and they do not make good pets. They need to be out in the wild doing what they are supposed to do — find the food they need to survive and feed their babies.” In fact, they travel so far that researchers have to use radio collars (颈圈) to keep track of them. The collars send out radio signals that tell people where the dogs are. No two wild dogs have the same pattern of coats, so it is easy to tell them apart.

    African wild dogs are smart and sociable, like pet dogs. Adult wild dogs, male and female, are willing to take good care of young ones.

    Millions of domestic dogs live on the planet, but there are probably fewer than 6000 African wild dogs left. Humans hunt them and farmers who don，t want them to go after cows and sheep poison them. Humans are also destroying the wild, natural habitat (栖息地) they need to survive in. Fortunately, today more farmers are finding other ways to protect their cows and sheep from African wild dogs instead of killing the animals.

    A new study of 8, 000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love (早恋) may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

    The possible reason for the connection between love and higher risk of depression for girls is "loss of self". According to the study, even though boys would say "lose themselves in a romantic relationship", this "loss of self" is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to their parents.

    Dr Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

    Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity gives us a chance to avoid its bad side effects.
